Applications of Chemtan A 60 in Industrial Manufacturing

Chemtan A 60 has established a specialized role in several industrial sectors due to its particular chemical profile. Below, we outline its precise use in key downstream segments, reflecting regulatory, formulation, integration, and finished product detail from an actual manufacturing perspective.

1. Chrome-Free Leather Tanning (Wet-End Processing)

Leather tanneries deploy Chemtan A 60 as a retanning and softening agent for chrome-free processing, especially in automotive and footwear leathers. Our technical teams support integration during the wet-end, following the pickling or vegetable tanning stage. Its dispersive effect helps uniform penetration, enhances grain tightness, and stabilizes dye fixation. Clients adapt concentration based on rawhide quality and desired softness, with effluent treatment aligned to international norms.

2. Synthetic Resin Emulsifiers (Acrylic & Styrene-Acrylic Dispersions)

Chemical manufacturers of waterborne resins utilize Chemtan A 60 as an anionic dispersing agent during emulsion polymerization of acrylic and styrene-acrylic systems. Its performance improves colloidal stability, prevents flocculation, and refines particle size control. Quality departments routinely validate the formulation through dynamic light scattering and viscosity benchmarks, ensuring consistency across production batches. The precise addition point and ratio depend on monomer hydrophilicity and batch scale.

Typical usage ratio

• 0.5%–1.5% (wt. of total monomers); ratio adjusted for resin solids content and final viscosity

Downstream process integration

• Dosed into the aqueous phase prior to initiator addition; mixed under high-shear agitation to stabilize particle formation during initiator feeding

Final product types

• Architectural coatings and paints
• Pressure-sensitive adhesives
• Paper and board coatings
• Nonwoven binders

3. Textile Sizing for Warp Preparation

Textile mills incorporate Chemtan A 60 in starch-based or synthetic sizing formulations to improve warp yarn abrasion resistance and weaving efficiency. Implementation involves pre-dilution and blending with other sizing ingredients like polyvinyl alcohol (PVA) and modified starch, with technical quality checks using viscosity and film adhesion testing. Integration supports high-speed weaving of cotton and blend yarns, reducing breakage and optimizing loom performance.

Industry compliance standards

• OEKO-TEX® Standard 100
• ZDHC MRSL (Version 3.1 for chemical input)
• ISO 9001:2015

Typical usage ratio

• 0.8%–2.2% (on total size composition), altered based on yarn type and blend ratio

Downstream process integration

• Introduced during size paste make-up, prior to application on warp beams through immersion or spray systems under controlled temperature conditions (65–75°C)

Final product types

• Woven denim fabric
• Home textile sheeting
• Synthetic fiber blends for technical textiles
• Shirting and suiting materials

4. Cement Grinding Aids and Additives

Cement manufacturers adopt Chemtan A 60 to reduce electrostatic agglomeration during clinker grinding and to improve particle distribution. The material enables improved mill throughput and energy efficiency, without introducing compounds that affect cement properties. Process engineers determine dosage based on clinker composition, humidity, and grinding unit performance, operating within safety and building materials legislation.

Industry compliance standards

• EN 197-1:2011 (Cement – Composition, Specifications and Conformity Criteria)
• ASTM C465 (Standard Specification for Processing Additions for Use in the Manufacture of Hydraulic Cements)
• ISO 14001:2015
• REACH compliance for processing additives

Typical usage ratio

• 0.02%–0.08% (wt. of total cement clinker), adjusted for specific surface area and mill operational parameters

Downstream process integration

• Injected as aqueous solution at clinker conveyor inlet or grinding mill feed, synchronized with clinker dosing system

Final product types

• Portland cement
• Composite cement (with fly ash or slag)
• Ready-mix concrete blends
• Specialty masonry cements

5. Paper Industry Wet-Strength Resins

Paper mills use Chemtan A 60 as a component in the preparation of wet-strength resins for tissue, label, and specialty packaging grades. It optimizes the dispersion of polyamine and polyamide-epichlorohydrin (PAE) resins, stabilizing colloidal charge and supporting continuous sheet formation. Quality laboratories monitor charge demand and drainage parameters, fine-tuning usage according to fiber content and paper machine speed.

Industry compliance standards

• BfR XXXVI (German Federal Institute for Risk Assessment, Paper and Board for Food Contact)
